DIC_ROCK_ALL (3677 rows)
Dictionary table based on the entire version 3 of the BGS Rock Classification Scheme and is populated directly from the 3 supplying tables (BGS.ROCK_NAME_V3, BGS.ROCK_COMPOSITE and BGS.DIC_ROCK_DUMMY). It contains both the base rock names and addditional codes required for specific application, eg. composite names for use on digital geological maps. It is formally approved as the official source of ALL database codes to be used in BGS corporate databases and MUST be followed.

| 286 | BLSTMY | RN | Blastomylonite - A type of mylonitic-rock. Blastomylonites are formed where extensive recrystallisation and mineral growth accompanied deformation, resulting, for example, in ribbon textures in quartzose rocks. British Geological Survey Research Report RR/99/02, section 7.3. | Blastomylonite | C | GRBA | 24-FEB-00 | TMCM | 22-FEB-19 | R | |
| 287 | BLTPH | RN | Block-tephra - A type of pyroclastic-sediment. In the Rock Classification Scheme, it is a pyroclastic-sediment in which the average size of more than 75% of the pyroclastic fragments exceeds 64 mm. Block-tephra, bomb-block-tephra, block-bomb-tephra, and bomb-tephra are separated according to the relative proportion of blocks (angular fragments exceeding 64 mm) and bombs (rounded fragments exceeding 64 mm): if more than 75% of all pyroclastic fragments bigger than 64 mm are blocks the sediment is block-tephra. It is the unconsolidated equivalent of pyroclastic-breccia.

| 293 | BNLIGN | RN | Brown-lignite - A type of lignite. It is brown with a dull or earthy lustre. Many are banded with a fibrous structure. British Geological Survey Research Report RR/99/03, section 6.1 and fig. 10. | Brown-lignite | C | GRBA | 24-FEB-00 | TMCM | 08-MAR-19 | R | |
| 294 | BOCOAL | RN | Bone-coal - A type of impure-coal with clay disseminated throughout the organic-matter. It can be recognised by its dull appearance and grey streak.

| 295 | BONIN | RN | Boninite - A type of high-Mg rock, classified using the total alkali silica (TAS) classification. The TAS classification may be used if the mineral mode of a normal fine-grained crystalline rock cannot be determined due either to the presence of glass or to the fine-grained nature of the rock. The definition of boninite is as shown in British Geological Survey Research Report RR/99/06, section 5.2 and figs. 17b, 22. | Boninite | C | GRBA | 24-FEB-00 | TMCM | 22-FEB-19 | R | |
| 296 | BORXST | RN | Borax-stone - A type of non-carbonate salt that is composed of particles of the borate mineral borax. British Geological Survey Research Report RR/99/03, section 7.1 and fig. 11. | Borax-stone | C | GRBA | 24-FEB-00 | TMCM | 08-MAR-19 | R | |
| 297 | BOTPH | RN | Bomb-tephra - A type of pyroclastic-sediment. In the Rock Classification Scheme, it is a pyroclastic-sediment in which the average size of more than 75% of the pyroclastic fragments exceeds 64 mm. Block-tephra, bomb-block-tephra, block-bomb-tephra, and bomb-tephra are separated according to the relative proportion of blocks (angular fragments exceeding 64 mm) and bombs (rounded fragments exceeding 64 mm): if less than 25% of all pyroclastic fragments bigger than 64 mm are blocks the sediment is bomb-tephra. It is the unconsolidated equivalent of agglomerate. British Geological Survey Research Report RR/99/06, section 4.2 and fig. 4. | Bomb-tephra | C | GRBA | 24-FEB-00 | TMCM | 15-FEB-19 | R | |
